8 Claims. 1
The invention relates to improvements in air ducts for automobile bodies, particularly bodies of the frameless or self-supporting type in which body and chassis are combined into one integral structure.
Among the objects of the invention is the formation of an air duct for automobile bodies which is simple in design and which requires a minimum of space.
These and other objects and advantages are achieved mainly by the novel formation of a brace of the body structure proper as air duct.
One embodiment of the invention is illustrated in the attached drawing in which,
Figure 1 is a fragmentary three-quarter front perspective and longitudinal middle section of the front end of a combined chassis and body structure;
Figure 2 is a similar perspective showing the body per Figure 1, certain parts of the air duct being broken away to reveal its interior construc- Figure 3 is a fragmentary section on a larger scale in the plane of line 3 of Figure 2, illustrating the connection between the main body unit and the inclined brace forming the air duct;
Figure 4 is a fragmentary outside view of the upper, rear end of the brace without cover plate and of an adjoining part of the wheel housing; and
Figure 5 is an inside fragmentary view of the rear end parts of brace and sill members and of the wheel housing, showing an additional air outlet.
It will be understood that Figures 1 and 2 show one side only of the body and that the other side is substantially symmetrical with respect to the longitudinal vertical middle plane of the body.
The front end of the body, fragmentarily shown in the drawing, comprises front post I4, cowl top 15, cowl side 16, floor panel ll, toeboard l8, and dashboard [9. The upper portion of the cowl side I6 is offset toward the longitudinal middle plane of the body. The offset portion has secured to its outside an outwardly facing channel section 2| provided with marginal flanges 22. Bottom wall 23 of section 2| and wall 20 behind it are provided with large registering openings 24.
A forward body extension comprises a longitudinal sill structure 25, a sill extension 26, an outwardly and rearwardly inclined brace 2'! emanating from extension 26, a vertical brace 28 interconnecting sill and brace 21, and an inner wheel housing wall 29 structurally secured to and formingpart of said sill and braces 25 to 28.
A recess between members 25, 26, 2'1, and 28, and a cut-out in wheel housing 29 serve for the reception of a transverse wheel-supporting beam 30, features which are more fully disclosed in copending application, Serial No. 133,353, "Cross Beam Attachment for Automobiles, of Alexander R. Lindsay, now Patent 2,636,774 issued April 28, 1953.
Rear margin of wheel housing 29 is secured to toeand dashboards l8, l9. Side sill member 25 extends rearwardly beyond wheel housing 29 and.
is secured to the underside of floor panel l6. The details of these connections are not illustrated; they may be substantially the same as disclosed in copending application, Serial No. 166,889, filed June 8, 1950, Alexander R. Lindsay, Final Connection Between Pre-Assembled Units of Self- Supporting Automobile Bodies, now Patent 2,662,794 issued December 15, 1953.
In final assembly the wheel housing 29 and sill 25 are connected with the main body unit, forming a compartment for the occupants, as disclosed in aforesaid Patent 2,662,7Q4, that is, a connection which can be made without reaching into the interior of the car. The final connection between the braces 2'! and the main body unit likewise does not require reaching into the interior of the car. This connection is made by overlappingly securing the flanges 3! of the brace 21 with flanges 22 of section 2 i as disclosed in an application Serial No. 195,264, Automobile Body, Parcover plate 34 presents a closed box-section which is used as air duct. Air is admitted to this duct through scoop or funnel 36 connected to front end of brace 21 and to inside of wheel housing 29. Funnel 36 extends through or adjoins the margins of opening 3'! in bafiie plate 38, and its interior communicates with the interior of brace 21 through openings .391provided in the top wall of brace Zlnear the front end thereof.
A further air outlet 4| may be provided, as shown in Figure 5, near the rear end of :brace 21 in front of the openings 33. Anadjustable valve, indicated at 42, may serve for directing the air or part of it to the outlet openings 33, or to the outlet 4|. The outlet 4| may be connected with heating or air-conditioning devices (not shown).
It is repeated that, while one side only of the body is shown, both sides are equipped with the illustrated brace structure, and both braces may he formed as air conduits.
The new construction has the advantage of great simplicity because one structure serves the dual purpose of structural brace and air conduit. It has the further advantage that no additional space is required for the air conduit. This lastnamed feature is sometimes of considerable importance because the space available for the motor and "itsaccessories is often rather limited anyhow and-would be still more limited if an air-conduit would have to be provided in addition to and on the outside of the reinforcing braces.
The invention is not restricted to the details and to the specific type of bodyconstruction illustrated in the drawing but is susceptible tomodii'leations. The invention may, for instance, be used at the rear end of a body.
